Abstract

The invention discloses an appearance leveling device for a PCB; the device comprises a tin pool, a clamp, an air knife assembly and an air suction assembly, the tin pool is used for containing metal tin melt, an opening is formed in the upper end of the tin pool, the clamp is arranged above the opening and reciprocates in the vertical direction, the air suction assembly is provided with an air suction opening, and blades are rotationally arranged in the air suction opening. After the blades rotate, hot air is extracted, tin-copper slag and volatilized scaling powder are sucked, a condensation piece is further arranged in the air suction opening, and the condensation piece adsorbs the scaling powder and separates out the tin-copper slag. The air suction assembly is arranged, tin-copper slag blown off by an air knife is collected through strong wind power while heat dissipation is conducted, the tin-copper slag is prevented from falling into a tin pool, and the influence of metal copper on the tin pool is effectively avoided; meanwhile, after the hot air passes through the condensation piece, the scaling powder can be rapidly cooled and separated out, and the scaling powder is prevented from being attached to all parts of the device and corroding important parts.

Description

technical field [0001] The invention relates to the technical field of PCB circuit board processing, in particular to a shape leveling device for a PCB circuit board. Background technique [0002] PCB (Printed Circuit Board) circuit board, the Chinese name is printed circuit board, also known as printed circuit board, is an important electronic component, a support for electronic components, and a carrier for electrical interconnection of electronic components. [0003] The printed circuit board is composed of an insulating base plate, connecting wires and pads for assembling and welding electronic components, and has the dual functions of a conductive line and an insulating base plate. It can replace complex wiring and realize the electrical connection between components in the circuit, which not only simplifies the assembly and welding of electronic products, reduces the workload of wiring in traditional methods, and greatly reduces the labor intensity of workers; it also ...
